Characterization of conductor by alternating current potential-drop method with a four-point probe
نویسنده
چکیده
A method of determining material parameters associated with a conductor using four points includes injecting and extracting alternating current into the plate using current-carrying wires operatively connected to two of the four points, measuring potential drop between the remaining two of the four points, and calculating the material parameters. The conductor can be of a homogenous material, a stratified material, or other type of material. The conductor can have any number of geometries, including that of a plate, a cylinder, a tube, a stratified cylinder or other shape.

Theory of four-point alternating current potential drop measurements on a metal half-space
An analytic expression describing the complex voltage measured between the pickup points of a four-point probe, in contact with the surface of a half-space conductor, is derived. The driving current is assumed to be time harmonic. There are two contributions to the measured voltage. One arises from the potential drop due to electric current flowing in the conductor. The other arises from induct...

An analytical expression for the voltage measured by a four-point alternating current potential drop (ACPD) method on a flat metal surface is derived. Far-field expressions for the electric field in a metal plate and in the region of the probe (air) are used to obtain contributions to the ACPD voltage from the metal plate and due to inductance in the pick-up circuit. The far-field approximation...
